Dietary Exposure tool - DietEx

The Dietary Exposure (DietEx) tool is a user-friendly tool for estimating chronic dietary exposure For the purposes of risk assessment, measurement of the amount of a substance consumed by a person or animal in their diet that is intentionally added or unintentionally present (e.g. a nutrient, additive or pesticide) to substances present in food, e.g. intentionally added or naturally present chemicals, contaminants, proteins, novel food Foodstuff or food ingredient that was not used for human consumption to a significant degree within the European Union before 15 May 1997 ingredients. It uses individual consumption data from the EFSA Comprehensive European Food Consumption Database to estimate dietary exposure for different countries, age groups (from infants to adults aged 75 years or older) and, for a limited number of countries, special population Community of humans, animals or plants from the same species groups (e.g. pregnant women, lactating women and vegetarians). The DietEx tool can be used by applicants, risk assessors as well as risk managers.

How DietEx works

Dietary exposure is estimated by multiplying, for each FoodEx2 category, the concentration levels input by the user with the respective consumption amount for each individual in the Comprehensive Database. The exposures per FoodEx2 category are subsequently added together to derive an estimate of the individual total exposure Concentration or amount of a particular substance that is taken in by an individual, population or ecosystem in a specific frequency over a certain amount of time per day and per kilogram of body weight (based on each individual body weight registered in the consumption survey). These exposure estimates are averaged over the number of survey days, resulting in an individual average exposure per day for the survey period. This is carried out for all individuals per survey and per population group, resulting in distributions of individual exposure per survey and population group. On the basis of these distributions, the mean and the 95th percentile A way of visualising the low, medium and high occurrences of a measurement (e.g. vitamin C intake) by splitting the whole distribution into one hundred equal parts of exposure can be calculated per survey and population group and in mg/day and mg per kg body weight/day.
